1'!) all wilt/fin, it 711/1151 concern:

-Be it known that I, Josnr KNors, master shoemaker, a subject of theKing of Prussia, German Emperor, residing at No. 121 Pontstrasse,AiX-la-Chapelle, in the Kingdom of Prussia, Empire of Germany, haveinvented certain new and useful Improvements in Proc esses ofManufacturingArtificial Fuel; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to i which it appertains to make anduse the same.

My present invention relates to 'a process for manufacturing artificialfuel consisting substantially of an amorphous coal obtained from thepeaty or turfysubstances of moors, bogs, or fens and of a flour won byboiling leather offal and grinding the resulting mass when dried. Afterboth ingredients have been thoroughly mixed in the desired proportionsthey are simultaneously heated and pressed into suitably-shaped cakes orbriquets.

To employ leather offal in form of chips as a binding means is not newin itself in the manufacture of artificial fuel; but then they Were usedas such and particular pains were taken to retain the shape of thechips.

The peaty or turfy mass composing moors, bogs, or fens is in the firstplace boiled to remove all juice contained therein, after which thepartly pulpy and partly granular mass obtained thereby is transformed inany suitable manner into amorphous coal by subjecting it to a glow heat.

To produce the leather flour employed as a binding means, leather offalis squashed,

l crushed, or otherwise preparatorily treated and then boiled, afterwhich the pulpy mass thus obtained is dried and then reduced to a flourby grinding or any other suitable mechanical operation. The leatherflouris then mixed with the amorphous coal in the desired proportion,and finally this mixture is brought into suitable forms, wherein it issimultaneously exposed to a glow heat and to pressure, whereby theparticles of the leather flour are -mechanically binding the particlesof the amorphous coal in such a manner that a transportable briquet isproduced.

The artificial fuel thus obtained is burning with a strong flame and islighter than the natural coal.

I I claim- The process for mamifacturing artificial fuel, consisting inboiling peaty substances to remove their juice, transforming theresulting mass into amorphous coal by exposing it to heat, boilingleather offal, drying the repowdery state, mixing the amorphous coalwith the leather flour, and finally uniting both ingredients totransportable briquets by simultaneously subjecting them to heat andpressure.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
